CAR HEATING AND VENTILATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 485,036, dated October25, 1892.

Application filed February 24, 1892. Serial No, 422,629. (No model.)

To all whom it may concern:

Be it known that 1, JAMES A. HEALY, of Nashville, in the county ofDavidson and State of Tennessee, have invented a new and Improved CarHeating and Ventilating System, of which the following is a full, clear,and exact description.

My invention relates to improvements in a system of heating andventilating railwaycars; and its object is to provide a simple andefficient means of heating cars by steam taken from the boiler of thelocomotive, to the end that no fire may be used around the car; toprovide an efficient means of ventilating the car, and to attach theheating mechanism in such a way that each car will have a completesystem of its own and that each' may be coupled in any part of the trainand be thoroughly heated and ventilated.

To this end my invention consists in certain features of constructionand combinations and arrangements of parts, which will be hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which the figure represents a broken verticallongitudinal section of a car provided with my improved system.

The car 10 is of the usual kind and may be of any ordinary construction,and in one end of the car is a small room 11, having a window 12therein, and this window opens into a small casing 13, in which is acoil of steam-pipe 14 and a rotary fan or blower 15 of the usual kind,the steam-coil being arranged between the window and the fan, so thatthe air entering the fan from the window will be first heated by passingover the steam-coil. The fan is driven by a belt 15"*, running over thefan-pulley and connecting with a grooved pulley 15 on the caraxle, thebelt extending through suitable slots in the car-floor. A hot-air pipe16 is connected with the fan or blower 15, and this pipe extendslongitudinally of the car and between the car-floors, the pipeconnecting near opposite ends of the car with registers 17, which openinto the car, and through which the heat from the hot-air pipe passes.The main steam-pipe 18 extends longitudi nally through the car and inthe upper part thereof, and if the car is provided with this system whenit is built the steam-pipe may be hidden in the roof of the car, orotherwise it may be bronzed or ornamented, so that it will look well.The ends of the steam-pipe project through the ends of the car andterminate in flexible hose 19, each hose having at its free end astop-cock 20, by means of which the hose and pipe may be closed, and thehose is adapted to couple with the hose of an adjacent car. The hose 19should be arranged centrally in the car, so that it will be sure to comeopposite to the hose of an opposing car, even though the cars might varyin width. A pipe 21, having a valve 21 therein, opens from the mainsteam-pipe 1S and con nects with the steam-coil 14, and the lower end ofthe coil terminates in a pipe 22, controlled by a valve 23, and the pipe22 enters a common form of steam-trap 24, which has a suitable vent-pipe25 opening from the pipe 22. Above the steam-trap is a valve-controlledpipe 26, and when live steam is used for heating the car the pipe 26 isclosed and the steam allowed to enter'the trap 24; but when the car isheated by exhaust-steam the valve 23 is closed and the steam is blownoff through the pipe 26.

Near the center of the car and opening through the roof is a common formof rotary ventilator 27.

The operation of the heating mechanism is as follows: The steam passesfrom the engine to the pipe 18 through any suitable coupling connection,and from the pipe 18 it passes through the steam coil 14:, and the airwhich enters the window 12 will be drawn through the coil by the fan orblower 15 and driven by the blower through the pipe 16 into the car. Acontinuous stream of pure warm air will be forced into the car and thefoul air will pass out through the ventilator 27. It will be noticedthat the air must constantly be supplied to the car while the car is inmotion, as the blower will be continuously operated because of itsconnection with the caraxle. A hand attachment may be provided to workthe fan when the car is not running.

I do not claim the detail construction of any of the mechanism shown inthe drawing, and I do not claim, broadly, the mechanism for heating acar by steam taken from a locomotive-boiler.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A car heating and ventilating apparatus 5 comprisinga train-pipe for the steam, extending through the upper part of the carand having suitable couplings at its ends, a'chamher in one end of thecar, into which abranch pipe leads from said train-pipe, a coil con- I0nected to said branch pipe in front of the airinlet or Window of saidchamber, two valved pipes leading from the coil through the bottom ofthe car and one of them provided with a steam-trap, and a blower in.said chamber operated from the car-axle and receiving the air afteritpasses the coil and provided with a hot-air pipe discharging into thelower portion of the car, substantially as set forth.
